Abstract: A system guides a user (or a vehicle 100) in reference to a target position via sound changes. The system (i) virtually disposes a sound source at the target position defined in a geographical data field covering the positional arrangement of the user and the target object, and (ii) actually outputs simulated sounds to the user as if the target position emitted sounds and the sounds were propagated from the target position to the user at the current position. The sounds change as the user moves in the geographical data field. For example, sound propagation paths, through which sound waves from the sound source are propagated to the user while being influenced by other objects or obstacles, are calculated based on positional data from a position detection system 10.

Abstract: A method for optimizing electromagnetic interference (EMI) comprising: an EMI analyzing step of analyzing a quantity of electromagnetic interference of an LSI by execution of simulation; a step of selecting an instance with a large quantity of noise in said EMI analyzing step; and a step of adjusting a driving capability of said instance so that it is lowered to an extent that a delay does not occur in a signal timing of said instance selected. In order to optimize the analyzed EMI, the portion for which optimizing is required is extracted, and such a measure as increasing the area where the decoupling capacitance is created is implemented for this portion in a necessary degree. Further, by changing the aspect ratio of the block, changing the block position or changing the cell line, the decoupling capacitance can be easily created at the most efficient inserting position.

Abstract: This invention is characterized to include a discrete analysis frequency width change specifying process for specifying in a particular frequency range a change in the discrete high-speed Fourier transform (FFT) analysis frequency width and a modeling process for allocating different discrete FFT analysis frequency widths to the specified frequency range and to a frequency range other than the specified frequency range and performing modeling. The EMI analysis method of this invention reflects on the gate level power supply current calculation the influence of decoupling by resistance, capacitance and inductance of the power supply and ground, thereby making it possible to evaluate the EMI of LSIs in simulation in a realistic time and to provide efficient EMI countermeasures through supporting the identifying of the EMI causing locations.

Abstract: A sound synthesis device is used for an interactive device which is capable of interacting with a user. The interactive device includes a pseudo-emotion generator which is programmed to generate plural pseudo emotions based on signals received by the interaction device. The sound synthesis device includes: (i) a sound data memory which stores a different sound assigned to each pseudo-emotion; (ii) a sound signal generator which receives signals from the pseudo-emotion generator and accordingly generates a sound signal for each pseudo emotion by retrieving the sound data stored in the sound data memory; (iii) a sound synthesizer which is programmed to synthesize a sound by combining each sound signal from the sound signal generator, wherein the user can recognize overall emotions generated in the interaction device; and (iv) an output device which outputs a synthesized sound to the user.

Abstract: In a mixed signal integrated circuit containing both an analog core circuit and a digital core circuit, a plurality of dedicated analog boundary scan cells disposed around the analog core circuit are connected in series by a dedicated analog boundary scan path. A plurality of dedicated digital boundary scan cells disposed around a digital core circuit are connected in series by a dedicated digital boundary scan path. The analog and digital boundary scan paths are independent of each other. In testing the analog or digital core circuit, the boundary scan path dedicated thereto is selected so that sets of test control data or test data are shifted only in the boundary scan cells dedicated thereto. As a consequence, a test pattern is shortened and the analog or digital core circuit can efficiently be tested in a shorter period of time.

Abstract: An arrangement for determining the position of a vehicle along a two dimensional course and for steering the vehicle to maintain a desired preset path. A sensing device is incorporated that includes markers placed at known locations and an optical sensor sequentially makes three measurements of the angle between the vehicle and the sensors, the angular course of the vehicle and the distance travelled from the last sensing so as to provide an indication of the actual vehicle position and course. The actual position is then compared with the desired position and corrections are made by the steering mechanism.
